Your body needs water to function properly. For example, water helps to regulate your body temperature, lubricate your joints, and remove waste from your body. Adequate daily water intake is very important. Furthermore, it is important to increase your usual water intake when you are ill, exposed to hot temperatures, or engaged in physical activities.
However, if your thirst is stronger than usual and continues even after you drink, seek medical help immediatelyâespecially if your thirst is accompanied by blurred vision and fatigue.
It is normal to feel thirsty after eating salty or spicy foods, or after engaging in strenuous exercise or sporting events, especially when it is hot. You may also feel thirsty when you suffer from diarrhea, vomiting, burns, or a significant loss of blood. Some prescription medications also cause thirst.

If you fail to replenish the fluids you lose and fail to respond to your thirst by drinking fluids, you can become dehydrated.
When you try to quench excessive thirst, it is possible to drink too much. Taking in more water than you expel is called overhydration, a condition that can occur when you have kidney, liver, or heart disorders or drink too much liquid to compensate for fluid loss. Overhydration can cause confusion and seizures.
